Gorm 调用 Save 方法，发现程序在方法内无限For循环

GORM Playground Link

https://github.com/go-gorm/gorm/pull/5920

Description

当我调用 save 方法的时候，突然发现程序一直卡死，导致请求timeout

  func (r *MuteRepo) Save(mute interface{}) (err error) {
    return Db().Save(&mute).Error
  }

虽然上面是一个错误的写法，但是对使用者来讲，如果这样调用会导致生产环境的崩溃，CPU飙升原因在下面的代码块 finisher_api.go 第 76 行开始

        reflectValue := reflect.Indirect(reflect.ValueOf(value))
    for reflectValue.Kind() == reflect.Ptr || reflectValue.Kind() == reflect.Interface {
        reflectValue = reflect.Indirect(reflectValue)
    }

reflectValue 恒等于 reflect.Indirect(reflectValue)，导致for循环一直存在可以考虑加一层判断避免上游代码的错误导致整个服务的异常

    reflectValue := reflect.Indirect(reflect.ValueOf(value))
    for reflectValue.Kind() == reflect.Ptr || reflectValue.Kind() == reflect.Interface {
        reflectIndirect := reflect.Indirect(reflectValue)
        if reflectValue == reflectIndirect {
            tx.AddError(ErrReflect)
            return 
        }
        reflectValue = reflectIndirect
    }
